Exoplanets, those planets outside our own solar system, can now be counted in the thousands thanks to past and ongoing surveys, e.g., Kepler [1]} and the Transiting Exoplanet Survey Satellite (TESS) [2]}. Follow-up observations of the most promising planetary targets with the Hubble Space Telescope, Spitzer Space Telescope, and ground-based facilities have thus far shown a wide range of atmospheric conditions. Many of these planets host atmospheres that have muted transmission spectra [3]}, indicative of significant and as of yet unidentified opacity sources in their atmospheres. Either condensate clouds or photochemical hazes in these atmospheres, or some combination thereof, are compelling candidates to explain the observed spectra [4]}, [5]}, [6]}, [7]}. As clouds and/or hazes are observed in our solar system on every world with a substantial atmosphere, the presence of such aerosols on extrasolar worlds comes as no surprise. Yet, the possibly unique compositions of these aerosols and the energetic regimes in which they are formed remain outstanding questions.
